CONNECTING SPEAkERS
• Be sure to connect speakers firmly and correctly
according to the channel(left and right) and the
polarity (+ and -). If the connections are faulty,
no sound will be heard from the speakers, and if
the polarity of the speaker connection is
incorrect, the sound will be unnatural and lack
bass.
• For installing the speakers, refer to "Speaker
placement" on page 10.
• After installing the speakers, first adjust the
speaker settings according to your environment
and speaker layout. (For details, refer to
"SETTING THE SPEAKER /ROOM EQ SETUP"
on page 56.)
■
Surround back speakers
• When using only one surround back speaker,
you should connect it to SURROUND BACK/
MULTI LEFT channel.
• Because this receiver cannot drive the surround
back speakers and the ROOM 2 speakers
simultaneously, you should assign their power
amplifier correctly depending on how to use
them. (For details, refer to "CONNECTING
ROOM 2 OUTS" on page 11 and "When
selecting the AMP Assign" on page 54.)
■
Front Bi-Amp Connections.
• Some speakers are equipped with two sets of
input terminals, for bi-amplification.
• If no other surround back speakers are used,
you can connect the FRONT and the
SURROUND BACK/MULTI channels to the bi-
amp-capable speakers. (For details, refer to the
operating instructions of your bi-amp-capable
speakers.)
• To drive the bi-amp-capable speakers, you
should assign the power amplifier to "BI-AMP".
■
Note :
• Before making bi-amp connections, remove the
short-circuiting bars from the terminals of your
speakers.
Caution :
• Be sure to use the speakers with the impedance
of 6 ohms or above.
• Do not let the bare speaker wires touch each
other or any metal part of this unit. This could
damage this unit and/or the speakers.
• Never touch the speaker terminals while the AC
input cord is connected to the wall AC outlet.
Doing so could result in electric shocks.
